Rated 5 out of 5 stars

This is my most used Thunderbird extension. I use it for scheduling emails to be sent at a later date. Thunderbird needs to be running for it to work and it has never failed me yet. Not a lot to say about it really, it just works. There are options to send send emails repeatedly and various other options that I don't use.

This review is for a previous version of the add-on (7.4.0).
